Why do we feel numbness in our legs when we sit down for a long time?
Numbness is anabnormal sensation that can occur anywhere in the body, but is most commonly felt in the hands, feet, arms, or legs. We may experience this as slight pricking (tingling) sensation in the limbs, if we leave our hand or feet in a single position for a long time. This supine or recumbent numbness is also referred to as the “limb falling asleep”. Sometime some minor objects like the wallet in our back pocket pressing against the nerves in our leg can cause our leg to fall asleep because there is direct pressure placed on the leg nerves and blood supply may be cut off because of squished arteries. This is called positional leg pain.
